Ultimate Ears MEGABOOM 3 Portable Wireless Bluetooth Speaker

In this review the Ultimate Ears MEGABOOM 3 is evaluated as a portable Bluetooth speaker for people who prioritize immersive, room-filling audio and rugged durability. The bottom line: this speaker delivers genuinely powerful 360-degree sound with deep, physical bass that works outdoors and poolside, and its IP67 rating and tough fabric make it a reliable companion for active users. The Magic Button and 20-hour battery life add convenient day-long usability for parties and outings, though a few reviewers note occasional Bluetooth quirks.

Key Features

• 360-degree sound: The speaker projects loud, clear, and immersive audio so listeners hear consistent detail no matter where they stand around the unit.
• Thundering bass: MEGABOOM 3 reproduces deep low frequencies you can feel, making it suited to bass-forward music and open-air environments.
• Magic Button: Play, pause and skip tracks directly on the speaker with a single press for quick control without pulling out a phone.
• IP67 waterproofing: The unit can be submerged for up to 30 minutes and floats, so it resists rain, pool splashes and dust during outdoor use.
• Rugged fabric and durability: A two-tone high-performance fabric and extensive durability testing mean the speaker withstands drops, tumbles and heavy use.
• Long battery life: Up to 20 hours of playback on a single charge supports full-day events or multi-hour outdoor sessions.

Who It's For

MEGABOOM 3 is ideal for listeners who want a portable speaker that competes with stationary systems on loudness and bass, and who take their audio outdoors-pool parties, beach days and backyard gatherings. The durable build and IP67 rating suit hikers, campers and active users who need a speaker that keeps playing through rough conditions.

Those seeking ultra-compact pocketable speakers, the absolute lightest travel option, or a perfectly stable Bluetooth link in every environment may want to compare alternatives; some customers report intermittent connectivity issues and the speaker is relatively large compared with small travel models.
